"Could the tape-out of these three chips be carried out at Xingyi Wafer Factory?"

As he said this, Director Qin was in disbelief.

Opposite Mr. Zhao was even more confused.

It is incredible to be able to develop a 40nm system-level chip and integrated baseband by itself, surpassing giants such as Qualcomm.

Have you ever achieved self-production?

Just kidding!

Do you really think that chip technology research and development is just like building a house, just say it?

Wang Yi smiled faintly: "Yes, it was taped out in our Xingyi wafer factory, so the yield rate is not very high. No, it happened to be a chip with insufficient yield rate. Kunpeng 702 lit up three times in a row.

success."

Mr. Zhao: "..."

Director Qin: "..."

The two looked at each other, big eyes and small eyes.

"Xiao Qin, you don't know about this?" Mr. Zhao frowned slightly, he made an oversight!

They thought that Xingyi Technology could only succeed in baseband tape-out, but it turned out that the SOC chip integrating baseband was also successful!

They thought that Xingyi Technology could at best realize the research and development and design of SOC system-level chips, and it turned out that it also achieved mass production!

Completely self-developed and produced!

The problem is that the authorities don’t know anything about such appalling achievements, not even Director Qin, who has direct contact with Wang Yi!

Totally overlooked!

Director Qin was also speechless: "How did I know about such an incredible thing? Damn it, I couldn't even dream of it! Leader, you really don't blame me!"

"Hahaha!" Mr. Zhao also laughed, very happily.

I also feel that Director Qin is really not to blame for this matter. If it were him, he would never have imagined that Xingyi Semiconductor could develop so fast.

But the problem is that it really happened!

It's just incredible.

"Awesome, really awesome, well done!"

Mr. Zhao was very excited and couldn't help but said: "Dr. Wang, what is the yield rate of your 40nm process?"

This is also critical.

Mr. Zhao thinks that if it lights up three times and succeeds once, it is estimated to be only 40 to 50%.

But it’s pretty good, after all, everything is difficult at the beginning.

Wang Yi smiled faintly: "The yield rate of 40 nanometers was 81% before, and we are still waiting for the results this time. The two leaders took a break for tea first, and are currently lighting up all the other chips for testing. They will be ready soon."

It can produce results.”

"No, no need, we're not thirsty."

"Yes, Director Wang, let's watch the lighting test together!"

"Okay!" Wang Yi smiled.

Then I returned to the laboratory with the two leaders.

At the scene, Xingyi Semiconductor workers were conducting tests.

During this tape-out, a total of 1,536 chips of the three types of chips were produced. Once the lighting test is completed, the yield rate of each chip and the overall yield rate will be known!

The surface area of ​​a 12-inch wafer is approximately 70,659 square millimeters, while the size of mobile phone chips is generally around 80-120 square millimeters.

Generally speaking, the area of ​​a chip without integrated baseband is about 80 square millimeters.

The integrated baseband chip is about 100 square millimeters.

Dividing the surface area, a 12-inch wafer can theoretically cut out 700 mobile phone chips.

But obviously, this is not realistic at all. The leftover materials from the wafer cannot be made into chips at all and will be wasted.

It is precisely because of this that the wafers are round instead of square, which would result in more waste.

After deducting the leftovers, only about 640 mobile phone chips can be cut out of a 12-inch wafer.

If the yield rate is 85%, that is 640*0.85=544 pieces.

If the yield rate is 90%, that is 640*0.90=576 pieces!

Of course, this is a system-level chip integrating CPU, GPU, baseband and other modules.

If it's just a separate baseband chip, it will be smaller.

Inside the SOC chip, the baseband only occupies about 10 square millimeters. But a separate baseband chip generally occupies about 30-70 square millimeters.

After all, a separate baseband chip and many modules cannot be shared with the processor, and all must be configured again.

The Kirin 990 with integrated 5G baseband is about 113 square millimeters.

The Kirin 980 without integrated baseband is about 75 square millimeters.

The external 5G baseband Balong 5000 is about 85.83 square millimeters. It is a very special baseband and one of the few basebands that is larger than the chip.

Kirin 980 + Balong 5000 add up to more than 160 square millimeters, which is much higher than the 113 square millimeters of Kirin 990 with integrated baseband.

This is the benefit of integrated baseband, which can save more space for other components.

Of course, Balong 5000 is an exception. Normal baseband chips are mostly 30-70 square millimeters.

Therefore, from the same 12-inch wafer, 1000-1500 baseband chips can be cut out.

The cost of baseband chips is also nearly half cheaper than the cost of SOC chips.

The reason why Qualcomm sells it so expensive is just to earn Qualcomm tax.

Or force users to give up purchasing chips from Nvidia and other friendly vendors and choose Qualcomm's processor chips + baseband chips.

Kunpeng 700 and Kunpeng 702 are both integrated baseband chips, and the area is naturally larger, about 100 square millimeters.

The baseband of Pterosaur 3000 is only 50 square millimeters.

This time, a total of two wafers were used to tape out, producing 512 Kunpeng 700, 512 Kunpeng 702, and 512 Wing Loong 3000.

Under the multi-person test, soon all the chips were lit and the test was completed.

Williams came over with the statistical results: "Chairman, the results are out."

"read."

"Kunpeng 700, 461 were successfully lit, with a yield rate of 90%."

"Kunpeng 702, 435 pieces were successfully lit, with a yield rate of 85%."

"Pterosaur 3000, 471 were successfully lit, with a yield rate of 92%."

“The overall yield rate of Xingyi Wafer Fab’s 40nm process is 89%!”

"So high!" Wang Yi beamed with joy.

Others were also excited.

The yield rate tested last month was only 81%!

This time, it has reached 89%!

I can only say that progress has been rapid.

"The 40-nanometer process is completely done!" Wang Yi looked at Mr. Hu with a smile and gave a thumbs up: "Mr. Hu is mighty!"

"Fortunately, I did not disgrace my life!" Mr. Hu smiled and breathed a sigh of relief.

Wang Yi thinks so highly of him that it would be unjustifiable if he failed.

"Well done! I must celebrate Mr. Hu, Williams, Pang Liguo, and the three teams!" Wang Yi said with a smile: "Tonight, I will be the host of a five-star hotel!"

"Thank you, Chairman." Everyone cheered.

They know that the five-star hotel is just the beginning. This month's performance and year-end bonus will be rewarded.

The team of George and Zhang Chao also became more motivated.

This time the Williams team has successfully developed Kunpeng 700 and Kunpeng 702, and will receive high bonuses.

But George's Kunpeng 901 team and Zhang Chao's Kunpeng 902 team do not have this honor.

Pang Liguo's 3G baseband team successfully developed the Pterosaur 3000 and will also receive high bonuses.

But the 4G baseband team does not have these benefits and has to wait until the 4G baseband is successfully lit!

Wang Yi implements quantitative management. Bonuses are not for one department to eat from a large pot, but are accurate to specific project teams and individuals.

A department, a different project team, and different breakthroughs will all receive very different treatment.

"Mr. Hu, I'll leave the mass production to you. Let's produce Kunpeng 702 first!" Wang Yi instructed.
